Verified user reviews

Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.

Email Verification API overview
What is Email Verification API?
Email Verification API is a real-time email verification tool that allows you to check the validity and existence of any given email address. Aside from ensuring that an email address follows the standard syntax and has an existing mail server, Email Verification API also performs email-sending emulation techniques. This process checks if the email address can receive emails via the Simple Mail Transfer Protocol (SMTP).
Email Verification API also provides a more advanced email validation process by checking if an email address is disposable or branded. With all these features combined, Email Verification API has been preventing more than 18 million bounce backs. To date, the tool has already verified more than 301 million email addresses.
Since the email verification service comes in the form of an API, users can integrate it into their web applications, marketing platforms, and other existing systems. Email Verification API is available in several programming languages with different client libraries, making coding easier.
